Abstract: The invention relates to addition compounds suitable for use as wetting agents and dispersants and obtainable by reacting monofunctional or polyfunctional aromatic epoxides with polyoxyalkylenemonoamines having a number-average molecular weight of >400 g/mol, one primary or secondary amino group and at least 4 ether oxygen atoms per molecule, from 90 to 100% of the epoxide groups of the starting material having undergone reaction, the weight fraction of aromatic groups in the addition compounds being not more than 50% and the addition compounds containing per molecule at least one amino group on which salts can be formed, or being present as a salt. The invention also relates to a process for preparing the addition compounds, to their use as wetting agents and/or dispersants and to pigments or fillers coated with the addition compounds and to pigment pastes which comprise pigments, binders and the addition compounds of the invention.
